SEWING-MACHINE BRAIDER OE CORDER.

Application filed April 6, 1912.

To all whom it may concern:

Be it known that we, HUBnir. M. Grnis'r, a citizen of the United States,and EMANUEL J. BorLnn, a citizen of Canada, and both residing at NewHaven, in the county of New Haven and State of Connecticut, haveinvented or discovered certain new and useful Improvements in Sewing-Machine Braiders or Corders, of which the following is a specification,reference being had therein to the accompanying drawing.

This invention relates to a sewing machine braider or corder, and hasfor its ob-' ject to provide an attachment of this kind which is of suchconstruction as to provide a convenient adjustment of the guidingpassage, so that the same may be readily varied for use in connectionwith braids or cords of different widths or sizes; as also to provide aconstruction whereby the braid or cord may be readily inserted into theguiding passage. To this end the body of the attachment is formed in twosheet metal parts, portions of which are so bent as to provide a guidingpassageway, one of these parts being adjustable relative to the other sothat the width of the said guiding passageway may be readily varied. Theadjustable part, in the preferred form of the invention, is acted on bya bell-crank lever one arm of which has a lip or projection engaging arecess in the said adjustable part, and the other arm of which ispreferably provided with a spring loop which embraces portions of bothof the sheet metal part-s of the attachment in such a manner as toafford a frictional grip on the two parts of sufficient strength tomaintain the said parts, and also the said adjusting lever, in anydesired position of adjustment. The improved braider or corder ispreferably adjnstably and detachably secured to a presser foot which is,in turn, adapted to be readily attached to a sewing machine presser bar.

In the accompanying drawing Figure 1 is a plan view of the improvedbraider or corder, and Fig. 2 is a front view thereof. Figs. 3 and t areopposite side views of the improved attachment.

Referring to the drawing 12 denotes a presser-foot provided with a shankportion 13 by means of which the said foot may be detachably secured tothe presser-bar of a sewing machine. The braider or corder Specificationof Letters Patent.

proper comprises two sheet metal parts or plates 14- and 15. The plate14, in the construction herein shown, is provided with an upwardlyextending flange or portion 16 provided with a key-hole slot 17 toenable the said flange or portion to be brought beneath the head 18 ofthe two-part clamping bolt 19 having a milled head 20 by which it may betightened and loosened, this clamping bolt construction being similar inoperation to the clamping bolt attaching device shown and described inPatent No. 900,067, dated Sept. 29, 1908.

In applying the braider or corder to the presser-foot the larger portionof the keyhole slot is brought into register with the head 18 of theclamping bolt, and the device is then moved laterally to bring the saidhead opposite any desired part of the narrow portion of said key-holeslot. From this it will be understood that when the clamping bolt isloosened the braider or corder may be adjusted laterally on the presserfoot, as circumstances may require, or may be readily removed from thesaid presser foot by again bringing the larger portion of the key-holeslot into register with the said head 18.

The front portion of the normally fixed part or plate 1 of the braideror corder is bent downward to form a lip 21 which is connected with thebody of the said part let by a vertical flange 22 which forms one sideor wall of the braid guiding passage, the other side or wall of saidguiding passage being formed by a vertical flange or lip 28 on theadjustable plate 15. The plate 15 is also provided with a horizontal lip24 overlying the guiding passage and having an upturned end beneathwhich a braid or cord may be drawn, when it is desired to insert thesame into the guiding passage, the said lip and the plate on which it isformed being of spring metal so that these parts will yield to suchpressure as may be necessary in inserting a braid or cord into thisguiding passage. The adjustable part 15 is also preferably provided witha small finger 25 extending across the front portion of the bottom ofthe guiding passage and entering a small aperture 26 in the verticalwall or flange 22.

Pivotally attached to the plate lat, by means of a rivet 27, is abell-crank adjusting lever comprising the arms 28 and 22 The saidbell-crank lever overlies the ad justable plate 15, the latter beingslotted for the passage of the rivet 27 so that the said plate 15 maymove laterally to a limited extent. The forwardly extending arm 28 ofthe bell-crank lever is provided with a downwardly extending lip 30which enters an aperture 31 formed in the said plate 15; and the freeend of the laterally extending arm 29 of the said bell-crank lever isformed into a spring loop 32 which embraces portions of both of the saidplates 14: and 15 in such a manner as to have a frictional grip thereon,so as to hold the said plates and the said lever in any desiredpositions of adjustment. That portion of the movable plate 15 which isbeneath the arm 29 of the said bell-crank adjusting lever is providedwith lips 33 embracing a portion of the stationary plate 14, so thatsaid movable plate will. be slidingly engaged with the said stationaryplate in such a manner as to maintain the side walls of the guidingpassage in par-' allel relation to each other in all posit-ions ofadjustment of the plate 15 relative to the plate 14-.

From the foregoing it vill be understood, that the width of the braid orcord guiding passage 34 between the walls afforded by the verticalflanges 22 and 23 on the fixed and adjustable plates 1 1- and 15 may bevaried by changing the position of the adjusting bell-crank levercomprising the arms 28 and 29, the lip 21 forming the bottom wall ofsaid guiding passage which is closed at its top by the overlying lip 24.It will also be understood that the said plates and the said lever willbe maintained in any desired position of adjustment owing to thefrictional grip afforded by the spring loop 32 on the arm 29 of the saidbell-crank le er, and which spring loop frictionally embraces portionsof both of said plates 14 and 15. The adjustment of the device, foraccommodating different widths or sizes of braids or cords, may bereadily and quickly effected without requiring such inconvenience anddelay as is incidental to the use of set screws heretofore generallyemployed in devices of this character in holding adjustable parts in anydesired positions in relation to each other.

. When the width of the guiding passage 34 is considerably varied it maybe necessary to adjust the braider or corder laterally relative to theneedle or the presser-foot, and in a plane transverse to the directionof the feed of the work, in order to maintain the variable guidingpassage in central aline-' ment with the notch or needle recess 35 inthe presser foot 12; and such slight lateral adjustment as may berequired, under these circumstances, may be effected simply by looseningthe clamping bolt 19 and adjusting the connected parts of the attachmentlaterally on the presser foot by virtue of the construction aflorded bythe narrower portion of the key-hole slot 17 in the up wardly extendingpart or flange 16 on the plate lt.

The invention is not to be understood as being limited to all thedetails herein shown and described, nor to any particular manner ofmounting the braider or corder proper on the presser foot. While theconstruction herein shown and described provides what is termed a topbraider it will be understood that it will. be within the present invention to so mount the parts of the attachment as to provide an underbraider if desired.

Having thus described our invention we claim and desire to secure byLetters Patent:
